If all of the items were accidentally displayed together without a sticker or label to mark their origin, what is the probability that you select a grain, fruit, or meat in your grocery basket, regardless if it's conventional or organic? First compute for yourself the row (i.e., n1+, n2+), column (i.e., n+1, n+2, n+3, n+4), and overall (i.e., n++) totals, to aid in answering the question.
